P a g e | 4311.3 Sample Security - 2009A variety of HQ, NQ and / or BQ size drill core was delivered daily from the drill rig to the Company’son-site core logging and storage facility near the small community of Arroyo Agrio in the north-easternpart of the claim block. Geotechnical and geological data was then recorded by company geologists,including recovery, specific gravity, rock quality designation (RQD), alteration defined by spectrometerreadings and specific geological rock type. Core samples were selected and marked by the samegeologists, with company technicians later using a diamond saw to half the core and secure each halfsample with self locking clips. Sample lengths varied generally from 1 to 3 metres long and up to 6metres in length and were chosen primarily along on recognized alteration or lithological boundaries.Three different standard reference samples, as well as locally derived ‘blank’ material and core duplicateswere inserted into each lab shipment in regular frequency; generally a different standard referencematerial every 20 samples, a blank every 80 samples and core duplicates every 20 to 30 samples. Acomplete library of split core remains protected inside a fenced compound near the small village ofArroyo Agrio (photo 5).11.4 Sample Preparation and Analysis - 2010/1011During the 2010/2011 drilling campaign conducted by Goldgroup samples of half core and riffle splitreverse circulation percussion chips from drill holes 10CBRC43 to 11CBN113 were collected from siteby Inspectorate and taken to their Durango preparation facility where they were dried, crushed and a 250gsplit was pulverised to -75 microns. The rejects were returned to site while the pulps were air couriered toInspectorate’s Richmond, BC, Canada facility and analyzed for gold by fire assay with AtomicAbsorption (“AA”) finish. In addition, a 30 element Inductively Coupled Plasma (“ICP”) analysis (aquaregia digest) was conducted on all samples.Samples of half core from drill holes 11CBN114 to 11CBN184 were collected from site by ALS Globaland taken to their Guadalajara preparation facility where they were dried, crushed and a 250g split waspulverised to -75 microns. The rejects were returned to site while the pulps were air couriered to theirVancouver facility and analysed for gold by fire assay with AAS finish. In addition, a 35 element ICPanalysis was conducted on all samples.11.5 Quality Assurance - Quality Control (QA-QC) - 2010/2011The three different standard reference materials used in this drilling campaign were prepared by CDNResource Laboratories Ltd. in Vancouver, Canada from mineralised material from the La Paila depositsupplied by Minera Cardel. Control charts suggest most all of the assay data on these three differentstandards fall within two standard deviation of the norm. Specific outliers exist outside 2SD, howeverthese are not considered influential to the overall data package.Standard GS-1E - 2% or 3 samples out of 163 – above / below 2SDStandard GS-P8 – 2% or 3 samples out of 161 – above / below 2SDStandard CGH-1 –1% or 2 samples out of 167 – above / below 2SDOne standard, one blank or one duplicate was inserted per group of 10 samples sent to the laboratory.11.6 Sample Security - 2010/2011A variety of HQ and/or NQ size drill core was delivered daily from the drill rig to the Company’s on-sitecore logging and storage facility near the small community of Arroyo Agrio in the north-eastern part ofthe claim block.
